ROLLER-BEARING.

Specification of Letters Patent.

. Patented NOV. 20, 1906.

Application filed December 29,1905. Serial No. 293,709.

' geles, in the count; of Los Angeles and State of California, haveinvented new and useful Improvements in Roller-Bearings, of which thefollowing is a specification.

This invention comprises a roller-bearing provided with bearing-rollersand separatingrollers mounted around the spindle of an axle,

said rollers being held in place on the spindle by tracks and rings,which prevent accidental removal of the rollers, said tracks beingmainly integral with the spindle.

An object of the invention is to provide a strong and simple bearing ofthis kind.

Another object is to provide such a bearing that can be readilyassembled and taken apart although solid retaining-rings are used.

in carrying out this invention the spindle ol an axle may be turneddown, leaving tracks thereon integral avith the spindle. 4 The tracksmay be simply integral with the spindle in the main portions ol saidtracks, a segment of the track being cut away and a detachable segmentinserted in the place thereof, as will be herciim-l ter more l'nllv setforth.

In some cases the tracks may be solid and integral with the spindlethroughout the. full circumference of the spindle. in such cases openrings of some known kind may be used to retain the rollers on thespindle.

The accompan' 'ing drawings illustrate the invention.

Figure l is a l'ragnlental sectional view illus (rating the." inventionas applied in the hub and on the axle ol a vehicle. .1" :11 in otherviews indicate tholine of section. Fig. 2 is a section on line 91:.Fig. 1. Fig. 3 is a section on line m at, Fig. 1. Fig. 4. is anenlarged l ragnicntal sectional view on line .1 Fig. 1, showing thedetachable block of the track.

Fig. 10 is an end view of therollcr-bearing in the process or assembling with the form of track shownin Fig. 1, the bearing-rollers all being shown in of has just beeninserted. Fig. 11 is an end view showing the parts in position duringthe process of inserting the separating-rollers. Fig. 12 is an end viewshowing the bearing after the rollers are in position,. showing methodof inserting the screw in theblock. Figs. 13 and let are views of thestripped bearing-and separating rollers, respectively. Fig. 15 is a viewof the spindle with the tracks i11- tegral therewith throughout. Fig. 16is a section on line 00 m1", Fig. 15.

1 designates an axle-spindle. 2- is the bearinghox; 3, the largebearing-rollers between the axle and box, said bearing-rollers beingprovided with notches 4 to receive tracks 5, that extend in the form ofannular shoulders or flanges around the spindle to prevent longitudinaldisplacement of the bearing-rollers '3 relative to the spindle.

6 desi nates the separating-rollers to separate the caring-rollers 3fro1n each other.

7 designates revolving rings in the notches 4 of the bearing rollers 3,said notches 4 being in the form of annular grooves containing saidrings 7 and the tracks 5. Each track may be constructed with adetachable section or block 8, dovetailed in a gap 9 and fastened by ascrew 10, screwed into the journal.

in order to allow the insertion of the block after the rollers areassembled around the journal and within the revolving rings 7, one largeroller 3 and one small roller 6 are stripped at each end to form asmooth spindle, as ll 12, that will not obstruct the placing of thesection of track in its place after' the rollers are inserted, as willbe hereinafter explained.

in case the track is sectional, as illustrated in Figs. 1' to 12, theblocks 8 will be detached for the purpose of assembling, leaving opengaps l) in the tracks 5. The 1 the rings 7 will be placed around theournal l at the tracks, respectively, and the large bearing-rollers willbe inserted one by one endwise through the gaps 9 inside the rings untilthe full quota oi" large rollers has been inserted one at a time throughthe gap and brought under the revolving rings. Then two of the largerollers at the gap will be spread apart, and a small roller (3 will beinserted through the gap under the ring, and then the large roller, witha separatiiig-roller at one side of thggap, will place as they appearwhen the last one there- K be rolled over beyond the gap, whereuponanother small roller may be inserted through the gap and under therings. Then another large roller will be rolled past the gap toward thelast-inserted small roller, and then another small roller will beinserted, as before, and so on-until the full quota of both large andsmall rollers has been inserted through the gap and under the rings.Then the stripped large and small rollers will be brought together atthe gap, and the blocks 8 will be slipped. along the stripped spindles11 12 and into place to close the gap 9-and will then .be fastened bythe screw 10, which can 'be inserted through the space between thestrippped spindles 11 12.

When the blocks for both tracks are thus secured, a roller-bearing hasbeen formed which is firmly connected with the aXle-spin-.

dle land is ready for the reception of the hub 13, having box 2, whichcan be pushed on and taken off at pleasure without disarrange ing therollers.

In the drawings, 14 designates thrust ballbearings at theends of thesleeve of the hub 13. 15 designates bearing-rings at the ends .ofsaidsleeve to engage the balls 16 of such bearing. a

17 and 18 designate dust-capsat the ends of the hubs to prevent dustfrom getting into .day of December, 1905.

known to the art and are not a part of my in vention, I have notillustrated the same.

What I claim is i 1. A spindleprovided with a plurality of annularflanges mainly integral therewith,

bearing-rollers and separating-rollers grooved to receive the flanges,and rings in said grooves for holding the rollers from displace mentfrom the'flanges.

2. A s indle provided with a plurality of annular anges, a section ofeach flange being integral with the spindle and another section beingdetachably fastened to the spindle, bearing and separating rollersgrooved to receive the'flanges, a bearing and a separating roller eachprovided with spindles at the ends to receive the flanges; and rings insaid grooves and outside said roller-spindles for. holding the rollersfrom displacement from the flanges.

3. A spindle provided with a plurality of annular flanges, a section ofeach flange being integral with the spindle and another section beingdovetailed therein, screws securing the dovetail sections in place,bearing'and separating rollers grooved to receive the flanges,

a bearing and a separating roller terminating in spindles outside saidflanges, and rings in said grooves and outside said spindles.

4. A roller-bearing comprising cylindrical rollers having grooves attheir ends and a spindle provided with. tracks or flanges at each endadapted to fit in said grooves, portions of said traoksor flanges beingremovable.

In testimony whereof I have hereunto set my hand, at Los'Angeles,California, this 22d I DELOS ALLEN.

In presence of- JAMES R. TOWNSEND, JULIA TOWNSEND.
